Leshykfrom soil microbes to model how they function and use carbon, ultimately helping to advance theClimate models are essential to predicting and addressing climate change, but can fail to adequately represent soil microbes, a critical player in ecosystem soil carbon sequestration that affects the global carbon cycle.
Soil microbes help plants access soil nutrients and resist drought, disease, and pests. Their impacts on the carbon cycle are particularly important to represent in climate models because they affect the amount of carbon stored in soil or released into the atmosphere as carbon dioxide during the process of decomposition. By building their own bodies from that carbon, microbes can stabilize it in the soil, and influence how much, and for how long carbon remains stored belowground.
Research focused on the microbes living around plant roots . This is an important environment to study because, despite being only 1-2% of Earth’s soil volume, this root zone is estimated to hold up to 30-40% of Earth’s carbon stored in soils, with much of that carbon being released by roots as they grow.
